Schneider Electric GT-1218 Ground Fault Sensor

Schneider Electric's GT1218 Ground Fault Sensor Current Transformer is the current-sensing element in Square D's GT-1218 ground fault protection system, providing the signal that the ground fault sensor uses to detect leakage faults in protected equipment. This current transformer is designed to integrate with Square D protection assemblies and serves as the standalone CT component in the GT-1218 family, branded under Schneider Electric/Square D. Also listed as Square D GT-1218 Ground Fault Sensor (B3) in some catalogs, the GT1218 is intended for use in electrical distribution applications where reliable ground fault monitoring is required to trigger protective action.
